Synopsis Academicians and intellectuals cannot remain inside the portals of their schools, colleges and universities by teaching and researching alone. What has been taught and research had on the institutions should have relevance, for which it is to be taken to the field for testing. This process of taking the new knowledge, concepts and skills from laboratories to the land or field is called extension. Thus, extension should form an integral part of education. This book “Extension – Third Dimension of Education” emphasizes this aspect. The book deals with various concepts, processes, strategies and the evaluation procedures to be followed in extension education. Hence, the book would be of great help to those who are already concentrating on extension such as teachers and students of Agricultural Colleges/Universities, Krishi Vigyan Kendras, Home Science College/Universities/Department, Adult and Continuing Education and Colleges of education. For those who have not yet, thought of the extension work as part of their programme it could be of a guide. This book will also help those who are involved in fieldwork.
